Almost 200 drivers have been arrested for drink or drug driving offences by Avon and Somerset Police in December.
There have been a total of 180 arrests as part of Operation Tonic - the annual Christmas campaign. Last year 231 drivers were arrested during the same period.
Drivers caught drinking and driving or driving while under the influence of drugs risk a fine of up to £5000, a minimum 12 month driving ban, a criminal record and could end up behind bars and without a job.
Police want motorists to take care during the build-up to the New Year celebrations. Anyone planning to go out and celebrate the New Year is being advised to nominate a non-drinking driver, arrange alternative transport and leave the car at home.
